Hardware accelerated algorithm for 2nd level trigger of very forward detectors at LHC

Data acquisition systems in High Energy Physics need to cope with increasing requirement of transmission bandwidth and storage capability. The LHC increase of luminosity and the bunch space reduction, after the first machine shutdown period, will produce more interactions per bunch crossing and increase the level of signal background. In this paper we present the design and study of second level trigger algorithms implemented in the data acquisition system of the TOTEM Experiment[1]. The project aims to increase the efficiency of the actual readout system by filtering on-line data, preserving the physics information of interest and better exploiting the available storage bandwidth.
